Why Does It Curdle? 

There are several reasons for why your buttercream frosting is curdling which can be very annoying. This will show the signs of curdled frosting. 

The Butter Is Too Cold 

When making buttercream, the butter is too cold it will mix as well into the other ingredients.

Therefore, you need to make sure the butter is at room temperature before using it. when creaming butter, it should be easy.

The butter also can’t be too soft and running as well because this will also leave the wrong texture for your buttercream. The butter part is just very important.

Too Difficult To Cream

The cold butter will make it too difficult to cream and the buttercream curdled instead.

You can heat up the butter to room temperature by popping it in the microwave for a short period of time to gently heat it. you need room temperature butter or a waterbath.

Using a hot water bath tends to work very well.

Important Tip

You should never just be taking it straight out of the fridge and into the bowl! This will help you reach a fluffy buttercream.

The Liquid To Butter Ratio

It is also very important because this is another way it can become curdled.

It needs to be both smooth and creamy to have the right texture, if there is too much liquid then it wouldn’t be creamy, but too slimy which wouldn’t sit on the cakes.

Not Enough Liquid

If there isn’t enough liquid in the mixture, then you will obviously need more liquid.

It will be very dry and there will be lots of lumps forming which is definitely not the right texture you are going for.

Therefore, you need to keep adding little bits of milk to your mixture until you reach a lovely smooth consistency. milk also works.

When you add too much liquid, the fat will start to separate from the solids. This means there will be a bit of mess. the buttercream curdles.


It is one of the most important parts of the baking process at every step. This is because, when you are mixing all of the ingredients together, it needs to be at room temperature.

If it is too hot or cold, it will curdle and not have that smooth texture you’re looking for and the split buttercream could happen.

Too hot

If you find that your kitchen is very warm, you might want to refrigerate your ingredients before using them slightly to bring them back to room temperature.

During the mixing process, if you can see it starting to curdle in the bowl, you need to put the bowl into the fridge before a bigger problem is caused.

This will bring it back to the right temperature and will smooth itself out. if not, you will find the buttercream has curdled.

Cold Environment

Check Your Environment

You also need to be checking your environment and everything to do with temperature before you start your baking. If you don’t know about this, then this could be a recurring problem when baking. 

Mixer Running

Your mixer can also be really important because you need to be able to use different speeds in this process to slowly and then build it up.
